Research Abstract

Mice with β_2 subunit-null mutations exhibited reduced cardiac muscle contraction in response to isoproterenol, and did not exhibit significant increases in Ca^2+ channel currents upon PKA-dependent phosphorylation. These findings indicate that the primary target for PKA by the sympathetic nervous system might be the subunit
